"Group and aggregate" I go back and forth on. As a plus, all of the relevant stuff is there. As a minus, it feels kind of disorganized because the aggs like var are there, the mono-aggs like std_by are there, and table methods like ungroup and partitioned_agg_by are there. If anything, I would consider subclassifying this section, but maybe it is ok to leave as is.

Maybe an overview is the way to handle this.
